2 things that I found that don't seem to have been mentioned -
1, after you complete a quest (I forget which one, might've been either Moonheart's or Amberclaw's, but I'm not sure on that), you can't put rabbits on the prey pile any more, and it appears as an empty stump that you can't interact with
2, you can only get one charisma point from teasing Bramblestar (I reran the game multiple times, basically just doing the tail shaking for maximum points, and only got one charisma point total, which was from the 'tutorial')
Side note, this game is amazing, as are all your others, and I will play it forever :)
